4 Single-board microcontrollers such as the BASIC Stamp, PICAXE, and Arduino and small-board computers like the Raspberry Pi have great potential for amateur radio applications. AMRAD is promoting the development of transmitters, receivers, test equipment, and station accesories utilizing microcontrollers.

7 * Karl, W4KRL, is developing a stand-alone touch screen LCD display controller for the miniVNA vector analyzer. He displayed a working version at the 2013 Vienna Wireless Winterfest. You can follow his progress on his website at <a href="http://www.w4krl.com/projects/"> www.w4krl.com.</a><br>

9 * Jeff, N6SDR, is exploring the use of an Arduino driving a stepper motor connected to a variable capacitor to remotely tune a magnetic loop antenna. Ultimately, the rig could communicate the operating frequency to the Arduino which would set the capacitor to the correct value with no tune up.
